“Money” slang. Any language. Any currency. Any denomination. Specific coins and notes, or in general.
You can specify these things if you like, but it’s not necessary. We have Google. 
What you got?

(As you can see I am not consistent with plurals. You don’t need to be either.)

“I keep a little skrill in my shoe.” I once had a co-worker who quite literally did :D.
Oh, and don’t forget the term** large**. Used to refer to denominations of $1000
e.g. “Sure, you can have this Beamer but it’s gonna cost ya 47 large.”
This ought to do it:
IN Canada, “loonie” for the 1 dollar coin, “toonie” for the 2 dollar coin.
In Quebec French, “cent noir” for the now non-existent penny, “cent blanch” for the dime, and “trente sous” (literally 30 cents) for the 25 cent piece.
From Wodehouse and other pre-War British books, I’ve picked up “the dosh” and “lolly”.
I still like to use “moolah” to mean a bunch of money, no specific amount or denomination.
Bob
Most famous in the Beatles Mean Mr. Mustard:
Mean Mister Mustard sleeps in the park
Shaves in the dark trying to save paper
Sleeps in a hole in the road
Saving up to buy some clothes
Keeps a ten-bob note up his nose
Actually spelled ducats although most of the rappers using the term would be hard-put to spell it.
Or most other words for that matter.
